SPECIFICATION forming part of Letters Patent No. 704,599, dated July 15,1902.

Application filed May l, 1901. Serial No. 68,756. (No model.)

To all whom it may concern.-

Be it known that I, KARL UNTERLEOHNER, a subject of the Emperor ofAustria-Hungary, residingat Gries, near Bozen, in the Empire ofAustria-Hungary, have invented certain new and useful Improvements inDevices for Fastening Windows, Doors, Sun-Blinds, and the Like in anOpen Position, of which the following is a full, clear, andexactdescription.

My present invention consists of a device forfastening windows, doors,sun-blinds, and the like in an open position, which is distinguishedfrom existing devices of the kind by its extreme simplicity and theabsence of springs.

As will be seen from the accompanying drawing, illustrating my inventionpartly in section, the device consists of two bars or arms rivetedtogether in the form of a cross and pivoted at d to a bar or plate 0,secured in the wall. One end of the bar 6 is provided with a hook e,which by engaging in the rabbet f of the frame 9 holds the window or thelike in an open position. In order to render the engagement of the hooke and rabbet f quite automatic, the bars a b are so pivoted to the baror plate a that the arm it acts as a counterweight. By means of the pin2' on the bar 0 the hook c is kept in a horizontal position and isprevented from swinging too far when turned about the pivot d. The end70 of the bar a serves as a handle, on pressing which in the directionof the arrow the hook will be released and the window can be closed. Inturning the cross in this manner the upper end of the arm will strikeagainst the frame g, giving it an impetus in the direction of closing.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-- Device for fastening windows, doors, sunblinds, and thelike, comprising in combination, a bar secured in a wall or the like;two arms connected together in the form of a cross, pivoted to saidfixed bar, and adapted to assume such a position that one of the arms isnormally horizontal and the other vertical; and a hook on the end ofsaid horizontal arm adapted to automatically engage with the front ofthe window, or the like, on opening said window, the upper end of saidvertical arm being adapted to strike against the frame of the window, orthe like, when the lower end of said arm is turned to release thewindow, substantially as set forth.

In witness whereof I have subscribed my signature in presence of twowitnesses.
